Ball valve itself is the main characteristics of compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, easy operation and maintenance, applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, widely used in various fields. Ball valve body can be a whole, can also be combined.

Design Features

Vertical split three piece body Can be disassembled without special tools, allows maintenance and repair of all inner parts.

Trunnion mounted ball Maintenan ce-free PTFE-coated bearings give low operating torque.

Floating pressure-supported single piston self relieving seat rings, soft seated The self relieving seat ring design prevents inadmissible overpressure in the body cavity.

Anti Blow out Stem

Prevents stem ejection by internal pressure when the stem packing retainer has been removed.

Double Block and Bleed

Both in open and closed position of the ball the body cavity is isolated from up- and downstream line pressure. This allows double block and bleed testing of the valve seals.

Drain Port

Enables draining the cavity and double block and bleed testing.

Anti Static Design

Prevents the building up of static electricity. This allows to use the valve also in explosive atmospheres.

Fire Safe Design, Fire Tested

Seat-to-body seals, stem packing and body seals are backed up with graphite se als. Fire tested according to international standards.
